I'll echo what many others have said - this is a great book, but the authors missed one major opportunity. It may be that at the time it was published the research on the topic wasn't robust enough, or maybe they intentionally left it out, but here it is:
- the extraversion spectrum
Where a child is extroverted/introverted or in between is going to have a major impact on how they experience the world, and how parents handle them. Like *major* impact. And yet the book only mentions the word 'introversion' once, commits the common fallacy that introversion is synonymous with shyness (it's not), and doesn't go into any depth at all about what introversion and extroversion actually are.
In my opinion this is a significant flaw of the book, and I hope if the authors ever put out another addition that they include detail on this topic, because it's something that almost no parent understands about their children.
Otherwise, the rest of it is great.
